ATTORNEYS United States Patent DISPENSING CONTAINER WITH FRICTION MOUNTED CAP Jack F. Fralick, Baltimore, Md., assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Application March 11, 1957, Serial No. 645,036

3 Claims. Cl. 220-42 The invention relates generally to metallic receptacles and primarily seeks to provide a novel container structure including a body, a breast seam secured on the body and a cap frictionally mounted on the container by having a skirt portion thereof frictionally engaging within a seaming chuck receiving channel of the breast.

Spray cans of the so-called aerosol type, or cosmetic dispensers, are commonly provided with removable caps which protect the spray valves or other dispensing devices from ingress of foreign matter. It is a purpose of the present invention to provide an improved container structure having an end or breast double seam secured on a body, said end merging through an upwardly and out wardly flaring chuck receiving wall into said seam, and there being included a cap having a lower end portion provided with a taper conforming to the flare of the chuck receiving wall and adapted to frictionally engage therewithin to hold the cap in place on the container and yet permit ready removal of the cap.

Another object of the invention is to provide a container structure of the character described wherein the tapered cap end portion terminates in an inwardly turned curl, and wherein the end or breast has an annular channel merging into the chuck wall and having a bottom conforming generally to the shape of the cap curl and in which said curl is adapted to seat when the cap is forced into full seating contact in its frictional mounting.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.

In the drawing:

Figure 1 is a side elevation illustrating a container embodying the invention, parts being broken away and in section.

Figure 2 is a plan view and part horizontal sectional view illustrating the container structure shown in Figure 1.

Figure 3 is an enlarged fragmentary sectional view showing the frictionally held cap bottomed in the chuck receiving channel in the breast.

In this example disclosure, a can body 5 and an upper end or breast 6 are joined by a double roll seam 7, the latter presenting an inwardly directed, upstanding and outwardly flared chuck wall 8. It has been found practical to provide a chuck wall having a 7 degree flare with relation to the adjacent body wall 5.

The chuck wall 8 merges in a smooth curve 9 inwardly and upwardly into the domed portion 10 of the breast in this particular illustration, and the breast has provision at 11 for receiving a spray valve means or other dispensing means (not shown) according to the nature of the use to which the can structure is to be put. It will be apparent by reference to Figures 1 and 3 of the drawing that the chuck wall 8 and the curved portion 9 of the adjacent domed portion 10 of the breast provide an upwardly opening chuck receiving channel.

A cap generally designated 12 is provided and has a skirt 13 which may be offset at 14, and which is inwardly and downwardly tapered as at 15 to provide a tight friction fit within the chuck wall 8. The cap skirt terminates in an inwardly directed curl 16 to which the taper 15 bears tangential relation, said curl being dimensioned to be received against the seat curve 9, or in other words to bottom in the chuck receiving channel whenever suflicient cap applying pressure is exerted to cause the cap taper 15 to enter the receiving and friction gripping flare of the chuck wall 8 to the extent required to bring about such bottoming of the curl 16. In Figure 1, the cap is shown as mounted by light pressure application, the curl 16 having moved only partially down over the depth of the chuck wall 8, and in Figure 3 the full seated application of the cap with the curl 16 bottomed in the chuck receiving channel is illustrated.

While one form of the invention has been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. In a can structure, a body circular in cross section and having a can end secured thereon by a double roll seam including an inwardly directed upstanding chuck wall outwardly flared at an angle of approximately 7 with relation to the axis of the body, and a cap having a lower end portion provided with a taper conforming to the flare of the chuck wall and adapted to frictionally engage therewithin to hold the cap in place and yet permit ready removal of the cap, said cap having an inwardly turned reinforcement at the end extremity of its lower end portion no part of which extends outwardly beyond the periphery of said cap taper, and said can end having an annular channel merging into the chuck wall in which said reinforcement is adapted to seat when the cap is forced into full seating contact in its frictional mounting.

2. In a can structure, a body circular in cross section and having a can end secured thereon by a double roll seam including an inwardly directed upstanding chuck wall outwardly flared at an angle of approximately 7 with relation to the axis of the body, and a cap having a lower end portion provided with a taper conforming to the flare of the chuck wall and adapted to frictionally engage therewithin to hold the cap in place and yet permit ready removal of the cap, said taper merging into and bearing tangential relation to an inwardly directed curl at the lower end extremity of the cap whereby no portion of said curl extends outwardly beyond the periphery of said cap taper.

3. In a can structure, a body having a can end secured thereon by a seam including an inwardly directed upstanding and outwardly flared chuck wall, and a cap having a lower end portion provided with a taper conforming to the flare of the chuck wall and adapted to frictionally engage therewithin to hold the cap in place and yet permit ready removal of the cap, said taper merging into and bearing tangential relation to an inwardly directed curl at the lower end extremity of the cap, and said can end having an annular channel merging into the chuck wall and having a bottom conforming generally to the shape of the cap curl and in which said curl is adapted to seat when the cap is forced into full seating contact in its'frictional mounting.
